DETAILED DESCRIPTION

Imaging devices may include a supply of a print material particleslocated in a reservoir. As used herein, the term “print materialparticles” refers to a substance which, when applied to a medium, canform representation(s) on the medium during a print job. In someexamples, the print material particles can be deposited in successivelayers to create three-dimensional (3D) objects. For example, printmaterial particles can include a powdered semi-crystalline thermoplasticmaterial, a powdered metal material, a powdered plastic material, apowdered composite material, a powdered ceramic material, a powderedglass material, a powdered resin material, and/or a powdered polymermaterial, among other types of powdered or particulate material. Theprint material particles can be particles with an average diameter ofless than one hundred microns, For example, the print material particlescan be particles with an average diameter of between 0-100 microns.However, examples of the disclosure are not so limited. For example,print material particles can be particles with an average diameter ofbetween 20-50 microns, 5-10 microns, or any other range between 0-100microns. The print material particles can be fused when deposited tocreate 3D objects.

The print material particles can be deposited onto a physical medium. Asused herein, the term “imaging device” refers to any hardware devicewith functionalities to physically produce representation(s) on themedium. In some examples, the imaging device can be a 3D printer. Forexample, the 3D printer can create a representation (e.g., a 3D object)by depositing print material particles in successive layers to createthe 3D object.

The reservoir including the print material particles may be inside ofthe imaging device and include a supply of the print material particlessuch that the imaging device may draw the print material particles fromthe reservoir as the imaging device creates the images on the printmedium. As used herein, the term “reservoir” refers to a container, atank, and/or a similar vessel to store a supply of the print materialparticles for use by the imaging device.

As the imaging device draws the print material particles from thereservoir, the amount of print material particles in the reservoir maydeplete. As a result, the amount of print material particles in thereservoir of the imaging device may have to be replenished.

A print material particles supply may be utilized to fill and/or refillthe reservoir of the imaging device with print material particles.During a fill and/or refill operation, the print material particlessupply can transfer print material particles from the print materialparticles supply to the reservoir of the imaging device.

The present disclosure relates to a print substance apparatus thatincludes a flexible cable to authenticate a print particle dispensenozzle. As used herein, a print particle dispense nozzle can be a deviceto fill/refill the reservoir of the imaging device. In some examples,the print substance apparatus can authenticate the manufacturer of theprint particle dispense nozzle and/or authenticate a type of printmaterial particles within the print particle dispense nozzle prior toallowing the print particle dispense nozzle to provide the printmaterial particles into the reservoir of the imaging device.

Forexample, the authentication mechanism can be a circuit assembly coupledto the dispense interface 108 to lock and unlock the mating interface102 via the locking mechanism.

In some examples, the print substance apparatus 100 can be utilized toreceive a print particle dispense nozzle within the rotatable matinginterface 102. For example, the print particle dispense nozzle can beinserted into an aperture of the rotatable mating interface 102. In someexamples, the rotatable mating interface 102 can include a circuitassembly that includes the electrical contact 106. In some examples, theelectrical contact 106 can correspond to electrical contacts of a printparticle dispense nozzle. In some examples, information relating to theprint particle dispense nozzle and/or contents of the print particledispense nozzle can be transferred through the electrical contact 106.In some examples, the electrical contact 106 can be an electricalinterface coupled to the mating interface 102 to receive a signal fromthe print particle dispense nozzle when the print particle dispensenozzle is inserted into the mating interface 102. As described herein,the signal can be received by the authentication mechanism toauthenticate the print particle dispense nozzle.

In some examples, the print substance apparatus 100 can be utilized toauthenticate the print particle dispense nozzle based on the informationtransferred through the electrical contact 106. For example, the printsubstance apparatus 100 can utilize the information to authenticate thatthe print particle dispense nozzle is from a particular manufacturer. Inanother example, the print substance apparatus 100 can utilize theinformation to authenticate that the print particle dispense nozzlecontains a particular type of print material particles. In this example,the print substance apparatus 100 can be utilized to transfer the printmaterial particles from the print particle dispense nozzle into a printmaterial particle reservoir of an imaging device.

In some examples, each type of print material particles can include aseparate print material particle reservoir within the imaging device. Insome examples, the print substance apparatus 100 can identify the typeof print material particles within the print particle dispense nozzleand determine if the print material particles within the print particledispense nozzle are compatible with a print material particle reservoirthat is coupled to the print substance apparatus 100. In these examples,the print particle dispense nozzle can be authenticated when the type ofprint material particles within the print particle dispense nozzle matcha type of print material particles within the print material particlereservoir coupled to the print substance apparatus 100.

In some examples, the print substance apparatus 100 can include adispense interface 108 that is coupled to the rotatable mating interface102. In some examples, the rotatable mating interface 102 can rotatewith respect to the dispense interface 108. In some examples, thedispense interface 108 can be stationary while the rotatable matinginterface 102 is rotatable in a first direction (e.g., clockwise, etc.)and/or a second direction (e.g., counterclockwise, etc.). In someexamples, the dispense interface 108 can include a port 110 that can becoupled to a print material particle reservoir of the imaging device. Insome examples, the mating interface 102 can include a first aperture toallow print material particles to be received by the dispense interface108 and the dispense interface 108 includes a second aperture or port110 to provide the print material particles to a print material supplyor print material reservoir of the imaging device. For example, thefirst aperture of the mating interface 102 and the second aperture orport 110 of the dispense interface 108 can be aligned when the matinginterface 102 is in the second position or unlocked position to allow aprint particle to pass through the first aperture and the secondaperture.

In some examples, the rotatable mating interface 102 can include a portthat can provide the print material particles to the port 110 of thedispense interface 108 in an open position and prevent the printmaterial particles from entering the port 110 in a closed position. Insome examples, the rotatable mating interface 102 can rotate to alterbetween the closed position and the open position. In some examples, therotatable mating interface 102 can be locked in a first position (e.g.,closed position) until the print particle dispense nozzle isauthenticated. When the print particle dispense nozzle is authenticated,the rotatable mating interface 102 can be rotated from the firstposition to a second position (e.g., open position).

In some examples, rotatable mating interface 102 can be locked in thesecond position (e.g., open position) until a signal is received by theprint particle dispense nozzle. In some examples, the signal canindicate that the print particle dispense nozzle is empty or hasdelivered a particle quantity of print material particles to the printsubstance apparatus 100. In some examples, the signal can unlock therotatable mating interface 102 and allow the rotatable mating interface102 to be rotated to the first position (e.g., closed position) suchthat the print particle dispense nozzle can be removed from therotatable mating interface 102.

In some examples, the print substance apparatus 100 can include a cover104. In some examples, the cover 104 can be utilized to protect therotatable mating interface 102 and/or components of the print substanceapparatus 100 from being damaged.

In contrast, when an object is“directly coupled to” or “directly coupled with” another element it isunderstood that are no intervening elements (adhesives, screws, otherelements) etc.

The above specification, examples and data provide a description of themethod and applications and use of the system and method of thedisclosure. Since many examples can be made without departing from thespirit and scope of the system and method of the disclosure, thisspecification merely sets forth some of the many possible exampleconfigurations and implementations.
